All of theaforementioned patent applications are hereby incorporated by referencein their entireties.

TECHNICAL FIELD

The disclosure relates to the technical field of simulated smoking, andmore particularly, relates to an atomizer and an electronic cigaretteusing the atomizer.

BACKGROUND

At present, the electronic cigarette has become a relatively maturesmoking substitute in the market, which supplies power to the heatingstructure in the atomizer through the battery device, so that theheating structure is electrically driven to heat the e-liquid togenerate smoke for the user to inhale,

In the traditional atomizer, since the liquid storage cavity and theatomizing cavity are communicated with each other, when the electroniccigarette is not used for a long time, the e-liquid in the liquidstorage cavity may enter the atomizing cavity and be absorbed by theliquid absorbing member. Since the atomizing cavity is communicated tothe outside, the e-liquid absorbed by the liquid absorbing member iseasy to volatilize to the outside, so that the liquid absorbing membermay repeatedly absorb the e-liquid in the liquid storage cavity. Whenthe user uses the electronic cigarette again, since part of the e-liquidin the liquid storage cavity has been absorbed by the liquid absorbingmember, the amount of the e-liquid in the liquid storage cavity isreduced, making it difficult to store the e-liquid in the liquid storagecavity. Further, since the atomizing cavity is also communicated withthe air inlet passage, when the amount of the e-liquid absorbed by theliquid absorbing member is saturated, the e-liquid in the liquid storagecavity may leak to the outside through the air inlet passage. Moreover,because the e-liquid is in contact with the air for a long time, it maycause the e-liquid to deteriorate and affect the user experience.

First Embodiment

Please refer to FIGS. 1 to 4, the first embodiment of the presentdisclosure provides an electronic cigarette (not shown). The electroniccigarette includes an atomizer 100 and a battery device (not shown). Theatomizer 100 is configured to electrically connect with the batterydevice. The atomizer 100 heats the e-liquid under the electric drivingof the battery device, so that the e-liquid is atomized into smoke.

The atomizer 100 includes a liquid storage assembly 10 and an atomizingassembly 20 installed in the liquid storage assembly 10. The liquidstorage assembly 10 includes a liquid storage cavity 11 and a liquidsealing member 12 disposed in the liquid storage cavity 11. Theatomizing assembly 20 is disposed in the liquid storage cavity 11. Theatomizing assembly 20 is provided with an atomizing cavity 21. Theatomizing assembly 20 can move axially relative to the liquid sealingmember 12, so that the atomizing cavity 21 is in fluid communicationwith the liquid storage cavity 11 or is isolated from the liquid storagecavity 11.

The liquid storage assembly 10 includes a liquid storage member 13, aventing member 14 disposed in the liquid storage member 13, and a liquidsealing member 12 received in the liquid storage member 13. The innercavity of the liquid storage member 13 is formed as a liquid storagecavity 11 for storing e-liquid, and a smoke outlet hole 131 is providedon the liquid storage member 13. The inner cavity of the venting member14 is in communication with the smoke outlet hole 131. The atomizingassembly 20 heats the e-liquid in the liquid storage cavity 11 under theelectric driving of the battery device, and the e-liquid is heated togenerate smoke. The smoke flows out sequentially through the innercavity of the venting member 14 and the smoke outlet hole 131, and theuser can inhale the smoke generated by atomization from the smoke outlethole 131.

The liquid storage member 13 is generally a hollow cylindrical structurewith an open lower end. The smoke outlet hole 131 is provided at theupper end of the liquid storage member 13. In this embodiment, theliquid storage assembly 10 adopts a pre-packaged manner, and thee-liquid is injected into the liquid storage cavity 11 in advance. Afterthe e-liquid is consumed, the atomizer 100 is discarded as a whole, andthe atomizer 100 cannot be refilled with e-liquid.

The venting member 14 and the liquid storage member 13 are twoindependent components, and the two are detachably connected by means ofsnap connection or plug connection. In one embodiment, the upper endsurface of the liquid storage member 13 protrudes downward along theaxial direction of the liquid storage member 13 to form a connectingportion 1311 around the smoke outlet hole 131. The venting member 14 issleeved on the connecting portion 1311. The connecting portion 1311 is ahollow structure, and the inner cavity of the connecting portion 1311 isin communication with the inner cavity of the venting member 14 and thesmoke outlet hole 131.

In one embodiment, the side wall of the liquid sealing member 12 abutsagainst the inner wall of the liquid storage cavity 11 to seal the openend of the liquid storage member 13. The upper end surface of the liquidsealing member 12 constitutes a part of the inner wall of the liquidstorage cavity 11. The liquid sealing member 12 is provided with amounting hole 121 for installing the atomizing assembly 20. The mountinghole 121 is in communication with the liquid storage cavity 11. Throughthe tight fit between the liquid sealing member 12 and the inner wall ofthe liquid storage cavity 11, the liquid sealing member 12 can be morefirmly connected to the inner wall of the liquid storage cavity 11, sothat the liquid sealing member 12 is fixedly installed in the liquidstorage member 13. Further, through the tight fit between the liquidsealing member 12 and the inner wall of the liquid storage cavity 11,the gap between the side wall of the liquid sealing member 12 and theinner wall of the liquid storage cavity 11 can also be sealed, therebypreventing the e-liquid in the liquid storage cavity 11 from leaking tothe outside through the gap between the liquid sealing member 12 and theliquid storage cavity 11. It is understood that, in another embodimentnot shown, the liquid sealing member 12 and the liquid storage member 13may also be integrally formed.

Please refer to FIG. 2, FIG. 5, FIG. 6, FIG. 7 and FIG. 8, the atomizingassembly 20 includes an atomizing housing 22 disposed in the mountinghole 121, a heating structure 23 disposed in the atomizing housing 22,an upper cover 24 installed at one end of the atomizing housing 22, anda seat 25 installed at the other end of the atomizing housing 22relative to the upper cover 24.

The atomizing housing 22 has generally a hollow cylindrical structurewith both ends being opened. In this embodiment, the atomizing housing22 is slidably disposed in the mounting hole 121 along the axialdirection of the mounting hole 121. The side wall of the atomizinghousing 22 abuts against the inner wall of the mounting hole 121. Theupper end of the atomizing housing 22 is movably connected with theventing member 14, so that the inner cavity of the atomizing housing 22is in communication with the smoke outlet hole 131. In this specificembodiment, the upper end of the atomizing housing 22 extends into theventing member 14. The cavity enclosed by the side wall of the atomizinghousing 22, the side wall of the venting member 14, the upper endsurface of the liquid sealing member 12 and the inner wall of the liquidstorage member 13 is the liquid storage cavity 11. The side wall of theatomizing housing 22 protrudes outward along the radial direction of theatomizing housing 22 to form a limiting protrusion 221. The limitingprotrusion 221 abuts against the upper end surface of the liquid sealingmember 12. At least one liquid inlet hole 222 capable of communicatingwith the liquid storage cavity 11 is provided on the outer peripheralsurface of the atomizing housing 22. In this embodiment, there aremultiple (e.g., three or more) liquid inlet holes 222, and the liquidinlet holes 222 are evenly arranged along the circumferential directionof the atomizing housing 22, so that the e-liquid in the liquid storagecavity 11 can evenly flow into the atomizing housing 22. The liquidinlet hole 222 is arranged close to the lower end of the atomizinghousing 22. In this way, when the amount of the e-liquid in the liquidstorage cavity 11 is small, the e-liquid located at the bottom of theliquid storage cavity 11 can also flow into the atomizing housing 22through the liquid inlet hole 222.

The heating structure 23 is disposed in the atomizing housing 22. Whenthe atomizer 100 shakes, the side wall of the heating structure 23 canresist the inner surface of the atomizing housing 22, so that theatomizing housing 22 can limit the radial displacement of the heatingstructure 23. The heating structure 23 includes a liquid absorbingmember 231 disposed in the atomizing housing 22 and a heating member 232contacting with the liquid absorbing member 231. In this embodiment, theliquid absorbing member 231 is wrapped around the heating member 232,and the liquid absorbing member 231 is interposed between the atomizinghousing 22 and the heating member 232. The outer peripheral surface ofthe liquid absorbing member 231 is attached to the inner peripheralsurface of the atomizing housing 22, so that the e-liquid in the liquidstorage cavity 11 can be smoothly absorbed by the liquid absorbingmember 231 through the liquid inlet hole 222. The heating member 232heats and atomizes the e-liquid absorbed by the liquid absorbing member231. The space of the heating member 232 for heating and atomizing thee-liquid is the atomizing cavity 21. In this embodiment, the heatingmember 232 is generally a hollow structure extending along the axialdirection of the atomizing assembly 20. The inner cavity of the heatingmember 232 constitutes the atomizing cavity 21. The smoke formed byheating the e-liquid by the heating member 232 is mainly located in theatomizing cavity 21.

The liquid absorbing member 231 is made of a material that is easy toabsorb liquid, such as cotton, cotton cloth or porous ceramics. Theliquid absorbing member 231 can gradually absorb the e-liquid flowingonto the liquid absorbing member 231 through the liquid inlet hole 222.In this embodiment, the liquid absorbing member 231 is cotton cloth.

The shape of the heating member 232 may be a heating net, a heatingsheet, a heating wire, etc. The heating net and the heating sheet canheat evenly, which can prevent local overheating. In this embodiment,the heating member 232 is a cylindrical spiral heating wire. The heatingmember 232 may be made of a material such as stainless steel,nickel-chromium alloy, or ceramics.

The upper cover 24 is disposed at the upper end of the atomizing housing22. The upper cover 24 is provided with an air outlet hole 241communicating with the atomizing cavity 21 and the inner cavity of theventing member 14.

The seat 25 is disposed at the lower end of the atomizing housing 22.The seat 25 is provided with an air inlet hole 251 communicating theatomizing cavity 21 and the outside. Two electrode contact members 252are provided on the seat 25 and spaced apart from each other, and thetwo electrode contact members 252 are respectively connected to two endsof the heating member 232. The two electrode contact members 252 areboth electrical conductors. Specifically, the two electrode contactmembers 252 are made of a conductive material such as iron, cobalt, ornickel. One of the electrode contact members 252 is used as a positivecontact, and the other electrode contact, member 252 is used as anegative contact. When the atomizer 100 is installed in place, theatomizer 100 and the battery device are electrically connected.

In this embodiment, the upper cover 24, the atomizing housing 22 and theseat 25 are independent components. The upper cover 24 and the atomizinghousing 22, or the atomizing housing 22 and the seat 25 are detachablyconnected by snapping connection or plugging connection. It isunderstood that, in another embodiment not shown, the upper cover 24,the atomizing housing 22 and the seat 25 may also be integrally formed.

Please refer to FIGS. 2 and 4, in this embodiment, the channelcommunicating the air inlet hole 251 and the atomizing cavity 21 is anair intake passage 253. The channel communicating the atomizing cavity21 and the inner cavity of the venting member 14 is an air outletpassage 141. The smoke formed by heating the e-liquid by the heatingmember 232 is located in the atomizing cavity 21. The outside air entersthe atomizing cavity 21 through the air inlet hole 251 and the airintake passage 253 to mix with the atomized smoke, and then, the smokemixed with the air flows out from the smoke outlet hole 131 afterpassing through the air outlet passage 141.

The battery device is detachably connected to the atomizer 100, and thedetachable connection includes, but is not limited to, snappingconnection, plugging connection, magnetic attraction connection, and soon. After the battery device and the atomizer 100 are assembled inplace, the positive electrode and the negative electrode of the batterydevice are electrically connected to the two electrode contact members252, respectively, so that the atomizer 100 can heat the e-liquid underthe electric driving of the battery device and make the e-liquid beatomized into smoke for the user to inhale.

In this embodiment, the atomizer 100 has a first state and a secondstate. Specifically, the first state is a state in which the atomizer100 is not assembled with the battery device, and the second state is astate in which the atomizer 100 and the battery device are electricallyconnected after the atomizer 100 and the battery device are assembled inplace.

In the first state of the atomizer 100, as shown in FIG. 2, the lowerend surface of the limiting protrusion 221 abuts against the upper endsurface of the liquid sealing member 12. The liquid inlet hole 222 isshielded by the liquid sealing member 12. The liquid sealing member 12prevents the e-liquid in the liquid storage cavity 11 from entering theatomizing cavity 21 through the liquid inlet hole 222.

In the process of assembling the atomizer 100 and the battery device,the atomizer 100 is gradually switched from the first state to thesecond state. Specifically, the battery device exerts a bottom-to-updriving force on the seat 25, the seat 25 moves upward relative to theliquid sealing member 12 in the axial direction of the liquid sealingmember 12, so that the atomizing housing 22 is driven to move upwardrelative to the liquid sealing member 12 in the axial direction of theliquid sealing member 12, and the liquid inlet hole 222 communicates theliquid storage cavity 11 and the atomizing cavity 21. When the atomizer100 is switched to the second state, as shown in FIG. 4, the liquidinlet hole 222 communicates the liquid storage cavity 11 and theatomizing cavity 21, and the e-liquid in the liquid storage cavity 11enters the atomizing cavity 21 through the liquid inlet hole 222.

When the battery device and the atomizer 100 are separated, the drivingforce exerted by the battery device on the seat 25 disappears. Due tothe gravity of the atomizer assembly 20 or by pulling the seat 25downwards, the seat 25 moves downward relative to the liquid sealingmember 12 in the axial direction of the liquid sealing member 12. Whenthe lower end surface of the limiting protrusion 221 abuts against theupper end surface of the liquid sealing member 12, the liquid inlet hole222 is shielded by the liquid sealing member 12. That is, the inner wallof the mounting hole 121 shields the liquid inlet hole 222, so that theliquid inlet hole 222 is staggered from the liquid storage cavity 11,and the atomizer 100 is switched from the second state to the firststate.

Please refer to FIG. 2 and FIG. 4, optionally, in order to facilitatethe atomizer 100 to switch from the second state to the first state, theliquid storage assembly 10 further includes an elastic member 15.Specifically, the elastic member 15 is a spring. The elastic member 15is disposed between the atomizing assembly 20 and the liquid storageassembly 10. Specifically, one end of the elastic member 15 abutsagainst the lower end surface of the connecting portion 1311, and theother end of the elastic member 15 abuts against the upper end surfaceof the upper cover 24. During the process of assembling the atomizer 100and the battery device, the battery device exerts a bottom-to-up drivingforce on the atomizing assembly 20. When the driving force is greaterthan the elastic force provided by the elastic member 15 on theatomizing assembly 20, the elastic member 14 is compressed, and theatomizing assembly 20 moves upward relative to the liquid sealing member12 in the axial direction of the liquid sealing member 12. As a result,the atomizer 100 is gradually switched from the first state to thesecond state, such that the liquid inlet hole 222 communicates theliquid storage cavity 11 and the atomizing cavity 21. When the batterydevice and the atomizer 100 are separated, the driving force exerted bythe battery device on the seat 25 disappears, and the elastic forceprovided by the elastic member 15 on the atomizing assembly 20 can causethe atomizing assembly 20 to move downward relative to the liquidsealing member 12. along the axial direction of the liquid sealingmember 12. When the lower end surface of the limiting protrusion 221abuts against the upper end surface of the liquid sealing member 12, theliquid inlet hole 222 is shielded by the liquid sealing member 12, andthe atomizer 100 is switched from the second state to the first state.It is understood that, in another embodiment not shown, the elasticmember 15 may also be a rigid and elastic element such as a thin steelsheet disposed in the inner cavity of the venting member 14, and thenumber of the elastic members 15 is not limited. Alternatively, theelastic member 15 may also be a cylinder made of a soft material withelasticity such as silicone or rubber.

Optionally, in order to improve the air tightness between the uppercover 24 and the connecting portion 1311, a sealing ring 242 issandwiched between the inner wall of the venting member 14 and the sidewall of the upper cover 24 to prevent air leakage. It is understoodthat, the sealing ring 242 is made of a material with good sealingproperty, such as silicone or rubber.

Specifically,the connecting ring 112 is sleeved on the connecting portion 1311, theventing member 14 is sleeved on the connecting ring 112, and the innercavity of the venting member 14 is in communication with the smokeoutlet hole 131. It is understood that, the connecting ring 112 may bemade of a material with good sealing property, such as silicone orrubber, to further improve the air tightness between the upper cover 24and the connecting portion 1311.

Optionally, in order to improve the tightness between the side wall ofthe liquid sealing member 12 and the inner wall of the liquid storagemember 13, or between the inner wall of the mounting hole 121 and theatomizing housing 22 so as to prevent the e-liquid in the liquid storagecavity 11 from leaking to the outside, in this embodiment, a firstsealing member 16 is provided between the side wall of the liquidsealing member 12 and the inner wall of the liquid storage member 13,and a second sealing member 17 is provided between the inner wall of themounting hole 121 and the atomizing housing 22. Both the first sealingmember 16 and the second sealing member 17 may be made of a materialwith good sealing property, such as silicone or rubber.

The battery device is detachably connected to the atomizer 200, and thedetachable connection includes, but is not limited to, snappingconnection, plugging connection, and so on. After the battery device andthe atomizer 200 are assembled in place, the positive electrode and thenegative electrode of the battery device are electrically connected tothe two electrode contact members 4512, respectively, so that theatomizer 200 can heat the e-liquid under the electric driving of thebattery device and atomize the e-liquid into smoke for the user toinhale,

Please refer to FIG. 10 and FIG. 12, in this embodiment, the atomizer200 has a first state and a second state. Specifically, the first stateis a state in which the atomizer 200 is not assembled with the batterydevice, and the second state is a state in which the atomizer 200 andthe battery device are electrically connected after the atomizer 200 andthe battery device are assembled in place.

When the battery device and the atomizer 200 are separated, the drivingforce exerted by the battery device on the seat 45 disappears, and theuser can pull the seat 45 downwards. When the pulling force is greaterthan the engaging force between the inner wall of the first latchinggroove 337 and the side wall of the protrusion 4531, the protrusion 4531disengages from the first latching groove 337, thereby causing the seat45 to move axially downward relative to the liquid storage member 33.Since the atomizing housing 43 is connected to the inner wall of theabutting portion 452, the seat 45 drives the atomizing housing 43 tomove axially downward relative to the liquid sealing member 32 when theseat 45 moves downwards. When the protrusion 4531 is engaged in thesecond latching groove 338, the liquid inlet hole 431 is shielded by theliquid sealing member 32 and the atomizer 200 is switched from thesecond state to the first state.
